Abstract

PURPOSE:To smooth operation by simplifying a structure, by assembling an apparatus frame by using a guide rail as a support and respectively supporting a spray gun and a balancer by both ends of a rope trained over two sets of pulleys and driving both of them up and down by a small air cylinder. CONSTITUTION:Four guide rails 1, 2 in a form erected at four corners of a recutangular shape are used as supports and cross frames 3 are arranged to form an apparatus frame. A pair of before and behind pulleys 18, 19 are respectively fixed to the upper surface of the machine frame and both ends of a wire 20 suspended so as to stradle the pulleys 18, 19 opposed in before-and- behind relation are introduced into the guide rails 1, 2 to suspend a spray gun support pipe 11 and a balancer support plate 13. A small air cylinder 21 is vertically provided directly under the center of the balancer support plate 13 and the supply of air is changed over by a change-over valve 24 to lift and fall a piston rod 22. By this method, the balancer support plate 13 is lifted and fallen and the pulleys 18, 19 re rotated to move a spray gun up and down.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a registration device for a paint spray gun for vertically expanding the spray range of paint in electrostatic painting or the like.

[Technical background of the invention and its problems]

When using a spray gun to spray paint onto an object being transported on a conveyor line, the object moves laterally and may also rotate, so the spray gun must be moved up and down at a fixed position. If the paint spray gun is moved, paint can be sprayed over the entire surface of a large object beyond the spraying range, so a registration device that moves the paint spray gun up and down is used.

The mainstream of conventional cashier processing equipment is one that uses an electric motor as a power source. However, if a fluid cylinder device is used as a power source, the control system described above can be made compact, and in particular, the use of compressed air used in the painting process can be improved in all respects. To compensate for the weak force of the air cylinder device, there is a registration device that uses a pulley and a weight suspended on the opposite side to smoothly raise and lower the spray gun using a small air cylinder. It has been proposed as a low-cost, high-performance product (
Patent application! ;rear. -01AI9KO).

[Purpose of the invention]

It is an object of the present invention to further improve the above-mentioned air cylinder system as a power source and a pulley-based registration device, and to provide a paint spray gun registration device that has practical capabilities.

[Summary of the invention]

In accordance with the above object, the present invention is configured as follows. That is, the device frame is constructed using Hiroki's guide rails standing upright at the corners of the square as supports, and the left and right side parts of the spray gun mounting member are guided by the guide rails on the front side of the frame so as to be able to move up and down. The left and right sides of the bulkhead member, which can reduce weight, are guided by the guide rails of the second tree so that they can rise and fall freely, and the pulley shaft is rotatably supported on the front and rear parts of the top surface of the machine frame. , both ends are provided with pulleys of the same diameter fixed respectively, two wires on the left and right are suspended across the pulleys facing front and rear, and the fly side part of the spray gun mounting member is suspended on the front ends of both wires, A paint characterized in that both sides of the balancer member are suspended from the rear ends of both wires, and the vertical movement of the spray gun mounting member is controlled by a small air cylinder device connected to the spray gun mounting member or the balancer member. This is a spray gun regipro device.

[Embodiments of the invention] The present invention will be described in detail with reference to the figures below.

FIG. 1 is a front view, and FIG. 2 is a side view.

First of all, Hiromoto's guide rail stands upright in the square Hiro corner.
The apparatus frame is constructed by arranging the horizontal frame 3 with /, Y, 2 as a support. The guide rails /, /, 2° are cylinders with vertical slits, and the front guide rails /,
/ means that the slit hole is placed in the front, and the guide rail on the rear side is placed, and - means that the slit hole is placed at the rear. Each guide rail /, /.

As shown in FIGS. 3 and 11, an elevating member 7 with rollers and rollers perpendicular to each other is housed in the elevating member 7, and a support platen extending from a portion thereof is housed in the elevating member 7, as shown in FIGS. 3 and 11. ,
q protrudes outside from slit a. Therefore, the front two guide rails /, / support brackets g and Ir go forward, the rear two guide rails and the second support platen)? ,9
protrudes backwards.

Both ends of the spray gun mounting pipe // are connected to the support brackets y and r via the connection bracket /θ, and the support platen)? , q are connected to both ends of the balancer support plate /3 via a connection bracket /2. In other words, the spray gun mounting pipe // is attached to the balancer support plate /3 on the front of the machine frame.
is installed on the rear of the machine frame so that it can be raised and lowered freely. /l indicates a spray gun, which is appropriately installed on the mounting pipe //. /S
shows a weight for increasing/decreasing heavy responsibility suspended from the balancer support plate/3.

Next, on the upper surface of the machine frame, two pulley shafts /6°/7 are rotatably suspended in the front and rear, and pulleys with the same diameter /g are attached to both ends of each.
, /9 are fixed. The leading edge of the front pulley /l is set to touch the center line of the guide rail /, and the trailing edge of the rear pulley /q is set to touch the center line of the guide rail. Both ends of the wire 200 suspended across the guide rails 9 are introduced into the guide rails 2 and connected to the upper ends of the respective elevating members 7. In this way, the spray gun support pipe l/ and the balancer support plate /3 are suspended from both ends of the pulleys 7g and /9. Adjust by increasing or decreasing the weight of the weight so that the total weight on both sides is equal.

A small air cylinder 2/ is provided as a relay directly under the balancer support plate/3, and the upper end of the piston rod is connected to the balancer support plate/3. Air hoses 23 are connected to the upper and lower ends of the air cylinder 2/, and the piston/rod 22 is moved up and down by switching the air supply through the switching valve 2/. Along with this, the balancer support plate /3 moves up and down, and at the same time, the pulleys /g and /9 rotate, and the spray gun /da moves up and down. Switching pulp 2q switching beam mitt switch 2! , 2! This is done by the signal.

Limit switch 2! ;, 2! The swing stroke of the spray gun 1 is adjusted by adjusting the position of ;, and the swing stroke is adjusted by the opening degree of the switching pulp 2.

〔Effect of the invention〕

As described above, in the paint spray gun registration device of the present invention, the device frame is assembled using guide rails as supports, and the spray gun and balancer are guided by the front and rear guide rails, respectively, and suspended from both ends of a rope suspended from one pulley. It is held in place and driven up and down by a small air cylinder, and the action of gravity is second only to moving the force, so it is very suitable for a small air cylinder.
It can be driven smoothly up and down at the same speed without impact. Since the equipment frame is constructed by using both the guide rail and the support, the structure is simple and durable. Also, since two pulleys are used, the diameter of the pulley can be reduced and the design can be made compact, making it suitable for electrostatic painting processes, etc. It is highly effective when used.
